The average revenues of 13 consecutive years of a company is Rs 82 lakhs . If the average of the first 7 years is Rs 77 lakhs and that of the last 7 years is Rs 89 lakhs, find the revenue for the 7^{th} year.

Solution & Step-by-step Explanation

Total revenue for 13 years = 13 \times 82 = 1066 lakhs Total revenue for the first 7 years = 7 \times 77 = 539 lakhs Total revenue for the last 7 years = 7 \times 89 = 623 lakhs Since the 7^{th} year is included in both the first 7 years and the last 7 years, it has been counted twice. Revenue of 7^{th} year = (Sum of first 7 years + Sum of last 7 years) - Total sum of 13 years Revenue of 7^{th} year = (539 + 623) - 1066 Revenue of 7^{th} year = 1162 - 1066 = 96 lakhs
